RECEPTACLE CLOSURE.

Application filed December 30, 1922. Serial No. 609,991.

To all whom it may concern:

Bev it known that I, AUeUsTUs L. lvlnnonnn, a citizen of the'UnitedStates, residing at Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in ReceptacleClosures, of which the following is a specification.

This invention relates to a receptacle closure, and an object of theinvention is to provide a closure of the simple screw type and in whichmeans is provided affording a. highly efficient linger grip for use inattaching and detaching the closure.

A further object is to provide a closure of this type having a wire-edgeformed thereon by turning up the material at the bottom of the flange,and having specially prepared parts disposed adjacent to the wire-edgeso as to reinforce the same against distortion and so as to cooperatetherewith in provid ing an eflicient finger grip.

A. further object is to so form the material of the flange of theclosure adjacent to the threads thereof as: to provide a desirableflexibility in said flange and threads so as to enable the threads tomore readily acconr modate themselves to the threads of the receptacle.Other objects and aims of the invention, more or less specific thanthose referred to above, will be in part obvious and in part pointed outin the course of the following description of the elements,combinations, arrangements of parts and applications of principles,constituting the invention, and the scope of protection contemplatedwill. be indicated in the appended claim.

In the accompanying drawings which are to be taken as a part of thisspecification, and in which I have shown merely a pie-- ferred form ofembodiment of the invention:-

Figure 1 is a side elevational view of a closure constructed inaccordance with this invention, the same being illustrated as applied onto a receptacle.

Figure 2 is an enlarged detail sectional view thru a portion of theclosure seen in Fig. 1.

Referring to the drawings for describing in detail the structure thereinillustrated the reference character L indicates the receptacle which isof course open at its upper end and which is preferably provided with anannular outstanding bead 1 thereon spaced downwardly from the upper endof the receptacle. Between the bead and the upper end is providedsuitable out-standing threads 2 with which the closure is intended toengage by interrotation of said parts in the usual manner.

The reference character G indicates generally the closure device, thesame being made up of a. cover part 8 and an annular-- marginal flange 4provided thereon for depending about the exterior of the receptacle. Theentire closure is formed from a single piece of sheet metal pressed ordrawn into shape, and the flange portion 4 thereof is pressed to providethe threads 5.

lt is to be particularly noted that the threads 5 do not extend'for thefull width of the flange but that on the contrary they are confined tothe central portion of the flange, i. e. to the region defined by thelines 6 and 7 in Fig. 2. The portion of the flange above the region ofthe threads, i. e. between the line (i and the top of the closure asdefined by the line 8, is formed with vertically extending corrugations9. While the portion of the flange below the threads. i. e. between thelines 7 and 10 is formed with a second series of vertical corrugationsas 11. the wire-edge 12 which, as will be seen in the drawing is formedby bending up the material of the flange. The lower portions of thecorrugations: 11 stand substantially in contact, with the upper portionof the wireedge and thus efficiently reinforce the wire-edge at alltimes.

The corrugations 1'1, projecting outwardly above the wire-edge alsoserve to protect said wire-edge against injury, and here it is to benoted, as shown by the line 13 in Fig. 2, that the corrugations 11preferably extend outwardly to substantially the same vertical plane asthe outermost portion of the wire-edgc so that in this way saidcorrugations 11 not only form a very eflicient protection for thewire-edge but also are given sufficient prominence so that they constitute an elticicnt linger grip.

It is also to be noted that by corrugating and distorting the materialof the flange adjacent to the lower portion of the threads there isprovided a certain appreciable degree of flexibility and elasticity insaid threads, and particularly in the lower por- Bclow the corrugations11 is formed may-be correctly,definedtherefore as float- .ingubetweenthe upper and-lower portions of the flange.

:It is alsopdesired. to note that whereas the corrugations 11 are formedsubstantially holly byvibeing pressed outwardly beyond the normal planeof the-flange, said plane .being indicated byLthe, double dotted line 141; in Fig. 2,-thecorrugations 9;:are formed by pressing thematerialofthe flange partlyoutwardofsaidfplane andpartly inward of said-plane. Bythis means the corrugations .11 are made-t0 project outwardly to agreater, extentthanthe corrugations 9 and a ;,correspondingand gracefulupwardly taper- Also ing appearance is given tojthe-closure.

- by-setting the corrugations 9 inwardly a certain crowding of thematerial is felt --Which materially increasest-he elasticity andvflexibility zof the-flange in and near the threads.

, Any vsuitable gasket as 15 may be provided withinthe closure ifdesired for improving thesealing, as :will be understood.

As many changes could be made in this construction without departingfrom the scopeof the invention as defined in the following claim, it isintended that all matter contained in the above description or shown inthe accompanying drawings, shall be interpretedas illustrative and notin a limiting sense.

Having thus described my invention, What I claim as new, andidesire tosecure by Letters Patent. is

A receptacle closure-coinprising coverfiand flangeportions, the materialof ;the flange being bentto provideithreads thereinspaced an appreciabledistance downwardly from the upper edge of the flange -thematerialsol?,the,flaugeibeiughalso bent to provide an outstanding wireedgospaced. an. appreciable distance below; saidithreads, and thematerial of the flaugezbeing also bent to providezoor- .rugationsextending vertically thereof. in
